study of gvax (with cy) and pembrolizumab in mmr-p advanced colorectal cancer

Conditions: Metastatic Colorectal Cancer

Summary: this study will be looking at the objective response rate (orr) as measured by recist in in patients with mismatch repair-proficient (mmr-p), advanced colorectal cancer that treated with cy/gvax in combination with pembrolizumab.
